Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed April 16, 1919. Serial No. 290,494.

T0 all whom t may concern Be it known that I, LAWRENCE D. SIBERT, a citizen of the United States, residingv at Jacksonville, in the county of Morgan and State of Illinois, have invented certain new and useful Improvements in Bookbinding, of which the following is a specification.

This invention comprehends improvements in bookbinding and the general obj ect of the invention is to provide a novel binding between the book sections, and the cover board so as to materially strengthen the construction and reduce the strain in the opening and the closing operations of the book.

The primary object of the invention is binding of the above stated character, which is durable and. efficient in use and one principally designed for use in connection with a whip-stitched book, whereby the units or sections constituting the body of the book may be firmly united with the cover.

A still further object of the invention is a device of the above stated character, wherein use is made of .a strip of material pasted or otherwise suitably secured to the blank with one edge thereof lapping the fold of the blank to facilitate the stitching thereto of the outermost units or sections of they book body.

Another object of the invention aims in providing a pair'of flaps adapted to be stitched together with the strip and certain sections of the book body.

With such and other objects in view, the invention comprises various novel features of construction and arrangement of parts which will hereinafter be set forth with particularity in the specification and the appended claims.

In the accompanying drawings, which illustrate one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views Figure 1 is a perspective view of a book, with the cover secured thereto.

Fig. 2 is a section taken on line 2 2 of Fig. 1.

Figs. 3 and 4 are detail perspective views of the binding elements removed.

Fig. 5 is a side elevation of one fold attached to one section of the book.

Fig. 6 is a view similar to Fig. 5, illustrating the reverse or opposite side.

Fig. 7 is a view of the fold in open position, and

`F ig. 8 is a section taken on line 8 8 of Fig. l.

In practice, whip-stitched books have been found to be advantageous, but difficulty is experienced in retaining the cover boards on the books, therefore the principal object sought is a binding for a whipstitched book which may be firmly'united or secured in its covers.

To this end, and in order that a clear understanding of the invention may be had, the book body, is here denoted by the character A embodying a. series of outer and inner sections or signatures B and C respectively united or connected to one another by a whip-stitch D.

Pasted or otherwise suitably secured to and lengthwise of the outside of a fold 6, which is the inside of the book lining, is a binding strip 7, preferably made of buckram, but if desired it may be constructed of any other suitable material, and this strip is of such width as to leave extended beyond the back edge 9 of the fold an extension 8. The extension 8 is lapped around said edge of the fold and initially pasted to the outside of the first or last section of the book body 10, as the case may be, so that the back edge of the fold is even with the back of the section. The extensions are then stitched to either of the outermost sections of the book to provide a exible hinge for the cover boards 11. The character 12, denotes aps. constructed preferably of buckram, or like material, and these fiaps are for ease in handling. pasted or fastened in pairs to the inner side of each of the outermost sections, as indicated at 13. with one flap arranged adiacent the top edge of the leaves and the other disposed in close proximity to the bottom of the leaves.

The opposite end 14 of each Hap is bent around the back edge of the said book section and stitched to the inside of the cover board beneath the lining 15 and under the strip 7. Previous to the operation of connecting the flaps with the cover board and the assembling of the body of the book composed of a series of sections, I punch 'all the sections. punching with the outer sections the extensions 8 of strips 7 and the two flaps where pasted on the book sections at 13,

I the flaps are pasted to the cover boards and wire stitched thereto as shown at 16; the vbook is then prepared for lining and the inside of the lining is pasted to the cover boards, leaving 17 of fold 6 as the fly leaf.

4The cloth covering of the cover boards is put on in preparing the book for the lining.

I desire to have it understood that even though the foregoing operation of binding books lis principally designed for rebinding "old books, magazines, newspapers and periodicals, the same may be used in binding books of any character, and provides a substantial, durable and eflicient binder sufficient -forextended use of books as in public or circulating libraries; and at the same time insures a greater flexibility between the body of the book and the cover. This construction further allows the cover to open more freely than usual, so ythat the strain between the first and second sections is reduced to a mnimum and there is less danger of the cover breaking away.

From the foregoing description taken in 'connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood, by those skilled in the art to which the invention appertains, and while I have described the principle of operation, to-

' gether with the article which I now consider to be the best embodiment thereof, I desire to have it understood that the article shown is merely illustrative and that such changes Amay be made when desired as fall within the scopefof the appended claims.

Having thus described the invention what I claim as new, is

l. A book comprising a series of sections, a cover therefor composed of a back-'and Aside boards, a -liningbetween each -of said side boards and the adjacent secti`on,'a strip secured to the outside of said lining, a pair of flaps stitched at one end between a pair of sections and through a sectionto'one edge of the strip, the oppo-site end of each flap lying beneath the strip and rigidly connected with the cover boards.

2. A book comprising a series of sections, a cover therefor composed of a back and side boards, a lining between each of vsaid side boards and the adjacent section, a strip secured to the outside of said lining with a portion thereof extending around to the inner side of the lining, flaps between two sections, a single row of stitching connecting the Vextended edge of said strip and one end of each of said aps to the sections of said book, and means for connecting the cover boards to said flaps.

3. A book comprising a series of sections, a cover therefor composed of a back and side boards, a lining between each of said side boards and the adjacent section, a strip secured to the outside of said lining with a portionthereof extending around to'the inside of said lining, naps-between two sections, a single row of stitching connecting the extended edge of said strip and one end of each of said flaps to a section Vof said book, the opposite end of said flaps being connected to the cover'.

In testimony whereof I affix my signature.

LAWRENCE D. srBERT.
